DESCRIPTION
The OPA622 is a monolithic amplifier component
designed for precision wide-bandwidth systems
including high-resolution video, RF and IF circuitry,
and communications equipment. It includes a mono-
lithic integrated current-feedback operational
amplifier block and a voltage buffer block, which,
when combined, form a voltage-feedback operational
amplifier.
When combined as a current-feedback amplifier, it
provides a 280MHz large-signal bandwidth at ±2.5V
output level and a 1700V/µs slew rate. The output
buffer stage can deliver ±70mA output current. The
high output current capability allows the OPA622 to
drive two 50or 75lines with ±3V output swing,
making it ideal along with the low differential
gain/phase errors for RF, IF, and video applications.

VIDEO SIGNALS
The feedback buffer stage provides 700MHz band-
width, a very high slew rate, and a very short signal
delay time. It is designed primarily for interstage
buffering and not for driving long cables. When com-
bined with the current-feedback amplifier section, the
OPA622 can be interconnected as a voltage-feedback
amplifier with two identical high-impedance inputs.
In this configuration, it features a low common-mode
gain, low input offset, and, due to the delay time of the
additional feedback buffer, a decrease in frequency
bandwidth compared with the current-feedback
configuration. Unlike “classical” operational amplifi-
ers, the OPA622 achieves a nearly constant bandwidth
over a wide gain and output voltage range. The
external setting of the open-loop gain with R avoids
OG
a large compensation capacitor, improves the slew
rate, and allows a frequency response adaption to
various gains and load conditions.
